  • The chameleon changes his colour;

    He can look like a tree or a wall;

    He is timid and shy and hates to be seen,

    So he simply sits down on the grass and grows green,

    And pretends he is nothing at all.

    - A. P. Herbert, 'The Chameleon'.

  • "'I'm going now, and you can vote. But remember, you are all potentially chameleons of the spirit, and thus of all the illusions that rob men of their divinity this is the cruelest; to call the rocklike burdensome shell of 'character' and 'individuality' man's greatest development. It's like praising a boat for its anchor.'"
